Waterproof membrane with a fabric-reinforced layer for ultimate fracture resistance.

Dex-O-Tex Neobond is a fracture-resistant, waterproof membrane designed for use beneath ceramic tile, marble, quarry tile, and certain types of troweled composition flooring. It consists of a proprietary Neoprene rubber emulsion with a fabric-reinforced cementitious layer for ultimate protection from cracking.

Apply Neobond between slabs or below grade and mold over bases and curbs for a tightly-adhering, waterproof surface.


  • Provides positive waterproofing
  • Reduces reflective cracking caused by substrate movement
  • Forms a monolithic, tightly-adhering, molded membrane across floors and up bases and curbs
  • Thin section, no depression of slab required
  • Can be applied over new or existing surfaces
  • Environmentally safe, contains no organic solvents and is VOC compliant
  • Installed only by professional, factory-trained Dex-O-Tex contractors
